Are You Drinking Coffee Too Early in the Morning? Neurologists Think So

""Right when your adrenaline hits, it kind of boosts the release of sugar stores from your liver, and then you get a crash. And if you haven't eaten anything, you can get hypoglycemic, which can make you really shaky on top of everything else.""

""The solution is to have a little complex carbohydrates and proteins. This might be anything from granola to peanut butter toast. The extra energy from the food will stop your body from crashing out mid-morning.""

""There's actually a genetic test you can take-it's the CYP1A2 gene-that can tell you if you're a slow or fast metabolizer of caffeine.""

""If you're experiencing racing heartbeats or palpitations, you probably have had too much caffeine. The same is true if you feel a hollow, heady combination of 'wired but also tired' in the afternoon.""

Adrenaline boosts sugar release from the liver, leading to potential hypoglycemia and shakiness if not managed. Consuming complex carbohydrates and proteins, such as granola or peanut butter toast, can prevent energy crashes. Caffeine metabolism varies among individuals, with a safe daily limit of 400 milligrams for most. Genetic testing can determine caffeine metabolism speed. Symptoms of excessive caffeine include racing heartbeats and feelings of being 'wired but tired' due to stress and sugar crashes.
